Letters Patent No. 108,106, dated October l1, 1870.

IMPRCVEMENT IN LAMPS:

The chedule referred to in these Letters Patent and making part of thesame Figure 2 is a side elevation of a slightly modified form of thesame. Y

My iniprovement relates more particularly to those lampsin which somematerial-is used to hold theoil by absorption, such as the chlorides,with whicht-he oil-pot oi' the lamp may be filled. These absorbingsubstances are employed for the purpose of holding the oil in ease ofaccidental breakage ofthe lamp, so that the oil will not spread and setfire to the surrounding objects. lt has been 1found necessary, whenabsorbente have been used, -to employ a tube w-hich would preventcontact of thc wick and the absorbing material, and such tubes have:always hitherto been iliade a part oi' the burner, which was onlycapable of removal when the protecting-tube should be removed likewise.This ias been found to be objectionable, because- First, the insertionof the protecting-tube, when the oil-pot is filled with an absorbingmaterial, is attended with ditiiculty.

Second, it necessitates the use ot' the particular style of burnermanufactured with the tube, when said burner may be very inferior.

Third, to till the lamp with oil requires a separate orifice, or theinconvenience of removing and replacing the tube at each illing.

These objections, which are vital, are all obviated by my improvement,which, therefore, consists in placing within the protecting-tube, acylindrical wielrtube, having an expanded top furnished withascrewthread, to receive any style of burner which may 'ne preferred.

` The invention alsoembraces an air-chamber surn` rounding thewick-tube, by means oi which the oil- .pot lis kept cool.

That others may fully understand my invention, I will particularlydescribe it.

The tube B is provided, at its upper end, with a screw-Harige, whichscrews iutothc collar on the oilpot. lhc tube B should extend nearly orquite to the bottoni of the oil-pot, and is surrounded by the chloride,or other absorbing substance employed. It willnow be observed that whenthe tube B has been once inserted, and the chloride is around it, itwill not be again removed so long as the absorbing material does notrequire to be renewed.

The tube B is closed at its bottom.

The tube E, opcn at both ends, is placed 1n the middle of the tube B,and extends through its bot-v tom, so as to eonununicatc with theoil-space, and a partitiointnbe, l), is placed between tubes B and E, soas to canse thc air to descend along the inner surface ot' B, and ascendto the burner along the outer surface 0i E.

The top of the tube E is expanded, and furnished with a screw-thread toreceive the screw of any burner of' proper size which it may bedesirable to use.

The tube E is made sntficicntly large to receive the wick from theburner without trouble, and the burner may be removed inthe ordinarymanner when the lamp to be iilled, Ithe oil being poured down 4the tubeE directly into the oil-pot.

From the above description, it will appear that my improyement is not animprovement in barriers, but

an improved safety-attachment to lamps, capable oi' usc with any lamp,and any style o'f burner. lhat when once applied it becomes a'ixtnre,while the burner may he put on or oli' as usual. That the lamp may befilled in the usual way, and without disturbing the absorbents. lhat thecurrent of air passing to the burner will keep the lamp always cool.Having described my invention,

What I claim as new is "lhe wiel: and filling-tube 1'), constructed witha screwfthreiul at. its top to receive the burner, as set forth,combined with the tube B, as set forth,and for the purpose described.
